With a 400k income, you're well-positioned to purchase a home in Washington. Financial advisors recommend spending about 3 to 4 times your annual income on a home, suggesting a budget between $1,200,000 and $1,600,000, depending on factors like your down payment and existing debts.

In Seattle, the median home price is approximately $900,000, which is below your minimum affordability range. This situation opens up a broad selection of homes, potentially allowing you to consider higher-end properties or homes in better neighborhoods.

Other areas such as Spokane and Tacoma offer competitive pricing at around $500,000. Washington's property tax rate averages 1.05%, adding roughly $9,450 annually on an average home. Coupled with a cost of living above the national average, your income provides ample opportunities for homeownership.
